This is an excellent and clever idea for solo gaming. It is a random dungeon deck. This deck has 50+ dungeon cards which represent the room or hallway discovered. these are drawn from the deck 1 per turn as the party moves from area to area. There are some ratings which gives the chance of finding treasuer, secret doors or the chance of getting an encounter or wandering monster. There is a strict order of play but it is not different from any RPG out there.
The monsters are generic and the player will need to consult the appropriate manual for there favorite RPG for the stats. Combat, of course, is also handled by the rules of the players RPG rather than the Dungeon deck. You can design your own encounters, treasures and search tables or you can get some prepared decks to add to this deck so you can accomplish all dungeon building tasks with the draw of a card and possibly the roll of a die. I also purchased the Hall of the Ogre Lord which has enough cards to fill out the Ogre Lord's hall and fight the evil minions within. It is an inexpensive way to try out the full system as you will only need Dungeon deck and Hall of the Ogre Lord to assemble all possible facets of the generator.
As already mentioned, THIS IS A DUNGEON GENERATOR! IT IS NOT A FULL GAME! YOU WILL NEED A ROLE PLAYING GAME SUCH AS DUNGEONS AND DRAGONS TO PLAY!
